NASCAR yanked Kyle Busch's keys after his reckless attack under yellow on Ron Hornaday during Friday's Camping World Truck Series race at Texas Motor Speedway.

While the race was under caution, Busch plowed Hornaday into the wall and effectively ended his quest for a NASCAR truck championship (Hornaday entered the race only 15 points behind the leader). It came moments after the caution came out for a jostling of Busch & Hornaday's trucks that brought both into contact with the wall.
